SPCIFICATION forming part of Letters 'iatent No. 470,524, dated IMarch8, 1892. l

'Y Application filed April 2B, 1888.

.To @ZZ whom it may concern.-

Be it known that I, RICHARD E. WARD- HAUGH, a citizen of the UnitedStates, residing at Jacksonville, county of Morgan, and State ofIllinois, have invented new and useful Improvements in Dust-Collectors,of which the following is a full, clear, and exact description.

This invention contemplates certain improvements in dust-collectors,having for its object to separate dust from air in an expeditious andthorough manner; andit consists of amr-approximately funnel-shapedreceptacle, within which is disposed a shaft driven by a wind-wheelthrough the current of air set up by the exhaust, said shaft carryingbrushes adapted to remove the dust from the inside of the receptacleinto a conveyer below, and also carrying beaters and a saucer,substantially as hereinafter more fully set forth, and pointed out inthe claims.

In the accompanying drawings, Figure 1 is a sectional elevation of myimproved dustcollector. Fig. 2 is a plan view of the reversible saucerwith its corrugated surface upward.

In the embodiment of my invention I employ a funnel-shaped receptacle A,suitably disposed to receive the dust. This receptacle or funnel isprovided at its lower convergent end with an outwardly and downwardlyared or enlarged chamber A', its upper converging end uniting with saidconverging end of the receptacle or funnel and its lower flared endpreferably having a marginal flange a.

B is an upright shaft disposed centrally in the funnel or receptacle A,and provided with a Wind-wheel b, arranged in the purified-air dischargeof the funnel or receptacle, and which is driven by the exhaust orcentrifugal force of the current of air as it is discharged from themachine. its lower end in a bearing or thumb-screw C, which is supportedin a screw-threaded plate c, held in one arm of a right-angled bracketd, depending from the funnel or receptacle A;

or it (the screw C) may work directly in the bracket. The shaft Bcarries a brush D,

which ranges with and removes the adhering dust from the innerconverging sides of the This shaft is stepped at4 Serial No. 272,206.`(No model.)

funnel or receptacle A into the lower chamber A', the dust then fallingor lodging in the Upon the shaft B, within the chamber A,"`

are secured a number of beaters or agitators F, which effect thedischarge or delivery of the deposited dust from the saucer E.

The saucer E, which prevents indrafts to the lower or bottom end of thefunnell or receptacle A'which would interfere with the outflowing dust,is adapted to permit of the passage through it of the shaft, and iscorrugated upon one side and smooth upon the other side. The saucer isalso reversible to permit of using either side upward. Being removablyheld upon the shaft B, it may be by nuts e screwed upon the shaft, oneabove and one below the saucer, or by means of shoulders upon the shaft.The corrugated side of the saucer is disposed upward to carry off, forinstance, sawdust, dac., when the invention is used in wheat-machines,planingmills, dac., the smooth side being placed upward in carrying offdust, &c.

To the upper part of the shaft B, within purified-air-outlet passage fof the funnel or receptacle A, is applied or secured a horizontal ortransverse rod or. bar G, upon which are carried two brushes I-I I-I toremove or clean the adhering dust from the walls of the outlet-passagef. These brushes are secured to sleeves or tubes g, which are fitted andheld upon the rod G by means of holding or thumb screws h. 4

It will be seen that by suitably manipulating the thumb-screw or bearingC, the shaft B, together with the saucer, beaters, and brush B, can all,simultaneously and at. one operation, be adjusted as may be required,while by means of the sleeve and thumb screw connection between therod Gand brushes H the latter can also be readily adjusted as occasion mayrequire.

It will be understood that I herein make no claim to any featuresforming the subjectmatter of the claims contained in my applicationfiled July 19, 1887, Serial No. 244,789.

IOO

I do not claim the combination, with thel tapering separating-'chamberprovided with van inlet for the dust-laden air, an outlet for l plied tothe smal-lend of the separating-chamber and surrounding the opening inthe apex thereof, nor the combination, with the taperingseparating-chamber provided with an inlet for the dust-laden air, anoutlet for' the j funnel having the enlarged lower end and the centralshaft, of the reversible saucer smooth purified air, and adust-discharge opening at its apex, of an enlarged dust-conduitsurroundingthe dust-discharge openingand separated therefrom by anannular shoulder surrounding the dust-discharge opening.

Having fully described my invention, what I claim as new, and' desire tosecure by Letters Patent, is-

l. The combination, with thefunnel or re'- ceptacle and the shaft, of.the saucer applied.

to said shaft andreversible'sidefor sidfe'fsub'- stantially as setforth. Y

2'. The combination, with the funnel orneceptacle and' the Wind-wheelshafty ad-justa'bly supportedy in place, of they saucer,.beaters,andbrush, all applied to'y andadj'ustable by means of said shaft,substantially as set forth.

- 3f. The combination7 with the funnel-'or receptacle and a loweroutwardly and downwardly ared chamber,i of the shaft carrying 4. Thecombination, with the funnel or receptacle and a lower outwardly anddownwardly lflared chamber, of the shaft carrying agitators or beatersarranged in said cham-ber and the saucer disposed upon saidv shaft justbelow the said chamber, substantially as set forth.

5. The combination, with the receptacle or I on one sid-e and corrugatedon the other side,

substantially as specified.

6'. The combination, with the' funnel or receptacle and the Wind-wheel,of the shaft oarrying a brush orb'rush'es arrangedin-theroutlet-passage.of said funnel or receptacle:

'7.- Th'e' combi-nation, with the funnel orV receptacle and the`Wind-wheel. shaft, of. lther brushes. having. applied; thereto'- sleevesor tubes provided. with thumbor'holdingscrews and a cross bar or rod.applied to said shaft and tting in said tubes or sleeves, substantiallyas set forth.
